What is the use of square steel keel or welding steel canopy
Sunshine board: advantages and characteristics of canopy cover top plate endurance detailed materials: flame retardant of spontaneous combustion temperature of 630 DEG C PC endurance board (wood 220 degrees C), by the national quality supervision and testing of fire building materials testing center, PC board of GB combustion (8624-1997 flame retardant grade B1), which belongs to the flame retardant engineering materials. Chemical corrosion resistant PC resistance board has good chemical resistance and corrosion resistance. It can resist all kinds of organic acids, inorganic acids, weak acids, vegetable oils, neutral salt solutions, aliphatic hydrocarbons and alcohol at room temperature. Heat resistant and cold resistant PC endurance board has good resistance to temperature difference. It can adapt to all kinds of severe weather changes from cold to high temperature. It can keep all kinds of physical performance indexes stable between -40 and 120 degrees centigrade. The photochemical PC resistance plate has the highest transmittance in visible and near infrared spectrum. Depending on the color, the transmittance is up to 12%-88%.
What material is most suitable for the construction of the canopySelect the canopy material, is the most important part of the awning construction, suitable materials, not only save money, and effort, but also worry. The awning material is usually divided into: "sunshine in canopy, canvas canopy, laminated glass awning, canopy tile".
Canvas awning: crank arm type retractable awning is in a separate structure, relatively safe, without the square tube, no paint spray, arm firmly and focus on both sides of the steel plate bracket, if the canopy length of more than 5m, the increase of direct arm assembly and focus on the middle support, on both sides of the iron with expansion screws are mounted directly on the solid wall, or welded firmly in indirect metal frame, the installation conditions need to pick out the roof, or rain gear plate, telescopic arm type awning is a retractable awning can be arbitrarily different stretching length, wind speed Aluminum Alloy bracket can withstand 50KM/ph. Maximum size of up to 18 meters wide, stretching length of up to 1.5 - 3.5 meters, the adjustment is divided into manual, electric, remote control and wind control, light control, rain control and many other ways for you to choose. Features: the main feature of this tent is cheap and practical. The sunshade cloth: generally equipped with ordinary canopy canvas, suitable for ordinary shops and small ordinary city.
